It has been another mild winter for the state of California. Much like last year the departures were above normal for most of the withdrawal season which has led to both PG&E and SoCal Gas having an abundance of inventory heading into this injection season. The past three weeks the state saw late season cold but that is coming to an end this weekend. This cold fortunately led to a delay in the refill activity which typically starts during the middle of March. Currently total PG&E storage inventory stands at 142 BCF which leaves only 70 BCF of injection room over the next seven months. SoCal Gas is in an even more difficult situation. The caverns currently have 52 BCF leaving 30 BCF available for injections. Both inventory totals are near historical highs for this time of the ... » read more

Last week's special report titled 'The Curtailment Conversation -2021' dove into the details around the CAISO, SPP and ERCOT renewable curtailments and the key factors that have this March escalating the year on year cumulative volume in each market.  We followed the report up with a briefing on each market via the EnergyGPS webinar that highlighted the report's content (the video recording and pdf slides can be found on the EnergyGPS homepage).  In both the report and webinar, the foundation is set to where the market fundamentals present more than ever in each market now that we are coming out of the winter season and headed into the spring.  The California market has been picking up momentum over the past few weeks as the power demand numbers are moderating and ... » read more

It’s been thoroughly rehashed by now that a failure of wind energy to produce when expected was not among the causes of the disaster in ERCOT during the mid-February storm. As we and others have pointed out, wind wasn’t expected to produce much at that time, so it wasn’t devastating to the grid when it didn’t. Little attention has been paid, however, to the performance of wind before and after the storm. In order to explore this in more depth, and in order to contrast the wind performance during the event with the conditions in the rest of the month, we’ve divided the month of February into three distinct periods: before, during, and after the event. Each period is so different they almost behave like individual months. Defining “the event” is ... » read more

The recent events across the middle third of the United States have brought the weather forecasting conversation to the forefront as several vendors have promoted themselves as have the tool that is able to predict what Mother Nature has in mind in the near-term and longer-term outlooks.  If you have been in the energy industry long enough, you quickly realize how volatile this process can be as there can be a whip-saw effect where one day the 1-15 day period is showing nothing but bearishness only to give way to a weather formation in northern portion of North America that gets the bulls riled up in a short period of time.  The one thing we are certain of, if this last year is any indication of what is to come, volatility and uncertainty is in order as we move out of the winter ... » read more

With global LNG demand market prices running at multi-year highs, U.S. LNG exporters are chomping at the bit to get as much gas out on the water as possible.  Recent days’ volumes are closing in on record highs and prospects look strong for those levels to be maintained through the summer.  Although spreads to ship into winter markets are even stronger than summer, U.S. exporters will have to wait to jam more volume into the market for new capacity to come online, which is not slated to happen until the end of this year.    Feedgas deliveries to U.S. LNG export terminals have returned to the 11 Bcfd level not seen since mid-December, when the single-day record high was set.  Following that event, January exports were fairly strong, though with sporadic ... » read more

In the past week we have heard a number of comments about the Texas demand destruction and how the state's economy has yet to make a full recovery in the aftermath of the energy crisis. The is being touted as reason why power burns have not performed anywhere near year ago levels. While it is true that the power burns in the EIA South Central have been a big disappointment this month it has nothing to do with ERCOT demand. If you look at the on peak demand versus temperatures for the past three years, this month is right on par with consumption in 2019 and 2020. So why is there a big drop off in the power burn component in the region? The burns are posting 1.6 BCF less than last year when COVID was impacting the economy.  Figure 1 | ERCOT On Peak Demand versus Houston ... » read more

The weather event this weekend had several micro systems brewing as the Midwest, Ohio Valley and Northeast all transitioned back into the winter mode after spending the past week basking in a spring-like setting.  Down in the South Central region, the wind gusts persisted as both ERCOT and SPP continue to deal with the volatile renewable resource across their respective footprints.  Over in California and the Pacific Northwest, we saw a combination of sunny skies and spurts of precipitation in the form of rainfall as temperatures were moderate as the clock changed to daylight savings.  The Rockies and Plains region was the area that received the most attention as the forecast was calling for a massive snow dump that would leave the mountains with over 4 feet of snow and ... » read more

As winter moves on to spring, weather turns milder, the sun comes out, and load declines, balancing the CAISO supply stack becomes a complicated problem. Because of the prevalence of solar, it’s useful to think about the daytime stack in three buckets:  Morning Ramp, Midday, and Evening Ramp.  It is the Midday period that catches the eye each and every day due to the massive influx of behind-the-meter and utility-scaled solar output there is on the grid.  The balancing act for the power demand profile is tricky as each hour is supplied with hydro, solar, wind, thermal, or nuclear generation, as well as imports from surrounding regions. The seasonal change affects this stack in more ways than one. Not only does load decline and solar increase, but snow stops piling up ... » read more

The one market that continues to take a backseat to both California and ERCOT is the Southwest Power Pool (SPP).  The name is a bit deceiving as one might attribute the footprint to the Desert Southwest, New Mexico and Nevada as these are the states that are tucked into the geography of the United States-Lower 48 as California stretches north to south and is identified by itself. Since the east and west electric grids are basically separated for reliability purposes, this leaves the former with say two-thirds of the country and since ERCOT's situation of being isolated from the rest of region has come to light over the past few weeks we have a similar situation as the latter where SPP is tucked away in the southwest corner of the outlined East region (left image) in Figure 1.

Just a few weeks after ERCOT set a 'theoretical' winter power demand record the thermal fleet was going to be pushing out generation that would have topped any record setting high water mark during a heat wave in July/August.  As we know, due to Mother Nature blasting the Lone Star State with extreme cold temperatures, such a scenario never came to light. As we settle into the month of March 2021, the grid could not be more 'polar' opposite as the power supply/demand picture is now showing the thermal fleet facing the potential for new low-side generation records.  Today through Sunday hosts the likelihood for hourly thermal generation levels drop to unprecedented lows as wind and solar surge to record highs. The upcoming event is not simply a function of weather ... » read more
